    Publication Year: 1990, Page(s):108 - 112
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (404 KB)

    It is shown that the percept of motion in depth interacts with the percept of static depth, and this interaction may result in small, but highly statistically significant, static depth distortions. This interaction fades with time, but persists at least one second. Specifically, an object that moves toward or away from the stereo cameras, and then stops, is perceived as being located in a differen... View full abstract»
